Abstract

The apparent presence of large core radii in Low Surface Brightness galaxies has been claimed as evidence in favor of warm dark matter. Here we show that WDM halos do not have cores that are large fractions of the halo size: typically, rcore/r200≲10−3. This suggests an astrophysical origin for the large cores observed in these galaxies, as has been argued by other authors.
